replaced aliased OpenGLExtension calls
replaced glCalls which used Extensions, that are aliased following OpenGL Specification.
I used a small powershell script to parse the OpenGL Spec gl.xml The script consists of less than 30 Lines of Code, and downloads the spec from github and deletes it afterwards. I also challenged @kschuster to do the same using python. Excited to see his results.
